<p>Photoconductive composition comprising a carbazole functional polymer wherein at least 0.1 percent of said carbazole function groups have the following structural formula wherein X is a structural unit of said polymer; R is hydrogen; an aliphatic hydrocarbon radical having from 1 - 10 carbon atoms; phenyl; or substituted phenyl, said phenyl substituents being capable of contribution of electrons to relatively electron deficient centers with the structural unit. Materials of the above structural formula can be readily polymerized or copolymerized with other addition polymers. these polymer compositions are useful in preparation of photoconductive insulating layers for electrophotography.</p> |
